The Precast/Prestressed Concrete Institute
has named Midwest Industrial Supply a Pre-
mier Partner, affording producer members
favored terms for the company's plant and
yard dust control solutions. Midwest has
partnered with PCI since 2015, working in
conjunction with the Institute to educate
members on best practices to meet revised
respirable silica dust exposure guidelines
set by the Occupational Health and Safety
Administration.
The updated Respirable Crystalline Silica
Standard for General Industry and Maritime
standard establishes a new eight-hour time-
weighted average permissible exposure limit
and action level, plus associated ancillary
requirements. The regulation enforces a
reduction in the amount of silica that workers
can be exposed to from 250 micrograms per
cubic meter of air to 50 micrograms. Employ-
ers are required to use "engineering controls"
such as vacuum dust collection or water-de-
livery systems to limit worker exposure to
respirable silica dust and use respirators as
required. Specified exposure control methods
are referenced in OSHA Table 1, which is at
the center of the new regulations for the con-
struction industry. Most provisions became
enforceable on June 23, 2018.
As the prestressed/precast concrete
industry leader, PCI recommends that orga-
nizations manage all aspects of construction,
including dust control, in order to reduce
harmful exposure to respirable crystalline
silica. By recognizing the efficacy of Mid-
west's silica dust control programs and the
company's overall achievements in the dust
control space, PCI will provide member orga-
nizations with a valuable resource for OSHA
Crystalline Silica Rule compliance, increased
worker safety, and better worksite efficiency.
